To ALLWHOM 1T MAY GONGERN: l

Be it known that I, JACOB G. DESHLER, of Allentowmlintie county of, Lehigh, and State of Pennsylvania, have invented a new and useful Improvement in Man-Powe-Machines; and I doL hereby-declare that the following is a full, clear, and lexact description thereof, which willienable others skilled in the art tomake anduse thesame, reference being had to the accompanying drawings,'forming part of this specification, in. which- Figure 1 is a top viewiof my improved man-powermachine.` I

Figiz'fe is avertici'rl vsefction of the saiethrougithe line z x, iig.

`Similar letters ofrreference indicate like parts. Y'

The object of this invention is to furnish a simple and eifective'machine for transmitting man-powerwith the leastfatigue to the operator.l

It consists of a vibrating foot-board, in eom-binationrwith a crank-shaft, and apair of double pitmen con- .necting the cranks of the crank-shaft, as will be hereinafter more fully described.

In the drawings, A is the vibrating foot-board, ailixdon a shaft, a, -thetrunnion-ends of which rest on the plates C, affixed to the frame J of the machine, and afford linearbearings tothe saidtrunnions, which bearings vallow a short rectilinear play tothe trunnion-shait, which lessens ,the tendency of v'the machine to catch on the dead-points or dead-centres, so called.

The rectilinear bearings also induce less friction than would the usual box-bearings.

On the trunnion-shaft are aixed two Pitman-beams, B, each of the ends of which is connected with a crank on the shaft by means o'f a pitman, D.

b is the crank-shaft, having four-crank-wrists, d, joining the crank-disk E E, E1GG G, and HH, as shown. To these wrists the pitmen D are coupled in any suitable manner. l

' I is a fly-wheel, and K is a pulley for4 transmitting the power obtained to'any work.

In using this machine, the operator stands on the board with a footon each sid'e of the centre of vibration, and by alternately leaning forward and backward, thusA bringing his weight on each side of the said centre of vibration, the machine is' driven. l A

Having thus described my invention, I claim as new, and desire to secure by Letters Patent-'f' The combination, in a man-power machine, of the vibratin'gfoot-board A, the trunnions of which vhave rectilinear bearings, substantially as described, with the pitman-beams B', pitman Dand crank-shaft b, all arranged and combined substantially, as shown and described for the purpose Vset forth.
